HOUSING' FOR SASH-PULLEYS.

' SPECIFICATION forming part of Letters Patent No. 544,196, dated Auguste, 1895.

I Application filed January 2, 1895. Serial No. 533,589. (No model.)

To all whom it may concern:

Be it known that I, JOHN H. SHULL, a citizen of the United States,residing at Wellesley, in the county of Norfolk and State ofMassachusetts, have invented a certain new and useful Improvement inHousings for Sash- Pulleys, of which the following specification, takenin connection with the accompanying drawings, is a full, clear, andexact description.

The invention has for its object to provide a housing thatis adapted toreceive a pulley with any form of periphery and that may be inserted inthe top of the frame after the latter is in place and having a seatvertically beneath the journal which rests squarely upon the top of thejamb, so that the entire load is borne by the j amb, and aninwardly-extending flanged arm which caps the opening in the frame andoverlaps the lintel for attachment thereto, while the housing and pulleyare both out of sight and the sash need not be plowed or cut away, as isnecessary when the pulley is at the side.

The invention will be understood upon reference to the accompanyingdrawings, in which- Figure 1 shows the. pulley and housing in use; Fig.2, a perspective view of the housing with a cord-pulley; Fig. 3, a planof the housing; and Figs. 4 and 5, sectional views of the housing, theformer showing the application thereto of'a band orribbon pulley and thelatter a chain pulley.

1 represents the housing, which affords a support for the journal 2* ofpulley 2 and at the same time covers the pulley, except on the lowerouterquarter, and prevents the displacement of the sash-support whichpasses over it. This housing is formed with a load bearing seat 3vertically beneath the journal 2, and a laterally-proj ecting flangedattaching arm or base 4, which'projects inward, caps the opening throughwhich the housingisinserted, and affords means of attachment. To betterconfine the sash-support, the pulley-encircling portion of the housingis extended to the point 1. The base has a passage 5 to admit thesash-supporting cord, band, or chain 6 in a vertical line tangential tothe inner side of the pulley, and a perforation 7 for an attaching-screw8. The housing is formed in two shells 1 1, having registering notch andtooth 1 Fig. 3, which are riveted together by the journal 2, andpreferably upon one of these shells is cast or otherwise formedintegrally the base 4, while the other carries a portion 4 of the base 4and has an overlapping lug 4 In putting the pulley in place the head orlintel of the frame is slotted at 9 sufficiently to admit the housing,after which the latter is inserted endwise and then turned up, so thatthe load-bearing seat 3 rests upon the top of the jamb or stile 10 ofthe windowframe and is prevented from outward displacement by theshoulder 3, while the inwardly-projecting base 4 is held up by the screw8 and prevents inward displacement.

It will be observed that the relative positions of the axis 2 and theload-bearing seat 3 are such that .no downward force is exerted upon thescrew 8, but rather an upward tendency is brought to bear at this point.The cord 6 or other sash-support passes vertically into the sash at 11,an auger-hole being all that need be made, and in this opening the cordis secured in any suitable manner.

The attaching-base 4 may be constructed either to lap on or becountersunk, so as to face with the lintel. My improved housing isconstructed for insertion or removal after the frame is in place, andcovers a sufficient portion of the pulley to prevent the cord fromdismounting when the pulley is in use. The

division of the housing, as shown, admits of its being supplied with anysize or design of pulley, either for rope, for chain, or for steelherein set forth.

2. In combination with the window frame, having the head-jamb slotted asshown to receive the pulley housing, the herein described housing inwhich the pulley is journaled, formed with a load-bearing seat 3 restingupon the top of the vertical stile of the window frame, in the slot andhaving the inwardly projecting lateral extension 4 lapping on or facingwith the surface of the head-jamb and covering the slot, as explained.

3. In combination with a Window frame, the herein described housing 1having a pulley journaled therein at 2, and formed with the load-bearingseat 3 at a point within the vertical line of the pulley journal, andthe shoulder 3 for the reception of the upper end of the vertical jamb10 of the window, and

provided with the laterally projecting base 4 I5 recessed at 5 for thepassage of the sash cord 6, substantially as and for the purposes setforth.

4. A housing for sash pulleys formed in two parts, each formed with aload-bearing seat 3 20 and one of which carries the lateral attachingbase 4, said parts being secured together by the pulley-journal, asexplained.
